There are no valves between the right atrium and the internal jugular vein. It follows that the degree of distension in the vein equates to the pressure in the right atrium and the venous waveform provides information about cardiac function.

The internal jugular vein enters the neck behind the mastoid process. Il runs deep to the sternomastoid muscle before entering the thorax between its sternal and clavicular heads. Because of its deep position the internal jugular vein can only be examined when the neck muscles are relaxed. Only a diffuse pulsation can be seen and the vein is not visible. The external jugular vein is visible but it is not routinely examined because it is prone to kinking and partial obstruction as it traverses the deep fascia of the neck.

IB Reclining at 45 degrees: point of transition between distended and collapsed vein can usually be seen to pulsate just above the clavicle. E Upright: upper part of vein collapsed and transition points obscured by sternum.
